Majority logic gate with non-linear input capacitors

ABSTRACT

A new class of logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates. Input signals in the form of digital signals are driven to non-linear input capacitors on their respective first terminals. The second terminals of the non-linear input capacitors are coupled a summing node which provides a majority function of the inputs. The majority node is then coupled driver circuitry which can be any suitable logic gate such as a buffer, inverter, NAND gate, NOR gate, etc. In the multi-input majority or minority gates, the non-linear charge response from the non-linear input capacitors results in output voltages close to or at rail-to-rail voltage levels. Bringing the majority output close to rail-to-rail voltage eliminates the high leakage problem faced from majority gates formed using linear input capacitors.

BACKGROUND

Typical logic gates such as an AND gate, an OR gate, or a logic gate that receives three or more inputs may consist of nine more transistors per logic gate and many interconnects to connect the various transistors. As the number of transistors increases, power consumption also increases. As devices are pushing down the power envelope to save battery power, existing circuit architecture for multi-input logic gates present challenges to the goal of lower power consumption.

DETAILED DESCRIPTION

Some embodiments describe a new class of logic gates that use non-linear polar material. The logic gates include multi-input majority or minority gates. Input signals in the form digital signals are driven to first terminals of capacitors with non-linear polar material. The second terminals of the capacitors with non-linear polar material are coupled to form a majority node (or a summing node). Majority function of the input signals occurs on this node. The majority node is then coupled to a capacitive node or device such as a gate terminal of a transistor. In various embodiments, this capacitive node is connected to a logic gate such as a CMOS circuitry, buffer, inverter, NAND gate, NOR gate, multiplexer, XOR gate, etc. The output of the logic can be used to drive additional multi-input majority or minority gates or to devices of other types of transistor technologies. The logic gate can be implemented in any suitable technology such as complementary metal oxide semiconductor (CMOS), tunneling field effect transistor (TFET), GaAs based transistors, bipolar junction transistors (BJTs), Bi-CMOS transistors, etc. As such, majority or minority gate of various embodiments can be combined with existing transistor technologies. In various embodiments, the summing node or the majority node has a signal which reaches rail-to-rail (e.g., from ground to Vdd) resulting in lower leakage in the subsequent logic gate. One drawback of using linear input capacitors, as opposed to non-linear input capacitors, is that the voltage on the summing node or majority output node does not reach rail-to-rail voltage, resulting in high leakage in the output driver or logic gate. Such issues are resolved by the multi-input majority or minority gates of various embodiments. In the multi-input majority or minority gates of various embodiments the non-linear charge response from the non-linear input capacitors results in output voltages close to rail-to-rail. Bringing the majority output close to rail-to-rail voltage eliminates the high leakage problem faced from majority gates formed using linear input capacitors.

There are many technical effects of the various embodiments. For example, extremely compact basic logic gates are formed using non-linear capacitors. The non-linear capacitors comprise non-linear polar material that can be ferroelectric material, para-electric material, or non-linear dielectric. The logic gates of various embodiments become the basis of adders, multipliers, sequential circuits, and other complex circuits, etc. The majority gate of various embodiments lowers the power consumption because they do not use switching transistors and the interconnect routings are much fewer than the interconnect routings used in transitional CMOS logic gates. For example, 10× fewer interconnect length is used by the majority gate of various embodiments than traditional CMOS circuits for the same function and performance. The capacitors with non-linear polar material provide non-volatility that allows for intermittent operation and zero power drain when not in use.

For example, a processor having such logic gates can enter and exit various types of low power states without having to worry about losing data. Since the capacitor with non-linear polar material can store charge from low energy devices, the entire processor can operate at much lower voltage level from the power supply, which reduces overall power of the processor. Further, very low voltage switching (e.g., 100 mV) of the non-linear polar material state allows for low swing signal switching, which in turn results in low power.

The capacitors with non-linear polar material can be used with any type of transistor. For example, the capacitors with non-linear polar material of various embodiments can be used with planar or non-planar transistors. The transistors can be formed in the frontend or backend of a die. The capacitors with non-linear polar material can be formed in the frontend or backend of the die. As such, the logic gates can be packed with high density compared to traditional logic gates. Other technical effects will be evident from the various embodiments and figures.

In the following description, numerous details are discussed to provide a more thorough explanation of embodiments of the present disclosure. It will be apparent, however, to one skilled in the art, that embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present disclosure.

Note that in the corresponding drawings of the embodiments, signals are represented with lines. Some lines may be thicker, to indicate more constituent signal paths, and/or have arrows at one or more ends, to indicate primary information flow direction. Such indications are not intended to be limiting. Rather, the lines are used in connection with one or more exemplary embodiments to facilitate easier understanding of a circuit or a logical unit. Any represented signal, as dictated by design needs or preferences, may actually comprise one or more signals that may travel in either direction and may be implemented with any suitable type of signal scheme.

The term “device” may generally refer to an apparatus according to the context of the usage of that term. For example, a device may refer to a stack of layers or structures, a single structure or layer, a connection of various structures having active and/or passive elements, etc. Generally, a device is a three-dimensional structure with a plane along the x-y direction and a height along the z direction of an x-y-z Cartesian coordinate system. The plane of the device may also be the plane of an apparatus, which comprises the device.

Throughout the specification, and in the claims, the term “connected” means a direct connection, such as electrical, mechanical, or magnetic connection between the things that are connected, without any intermediary devices.

The term “coupled” means a direct or indirect connection, such as a direct electrical, mechanical, or magnetic connection between the things that are connected or an indirect connection, through one or more passive or active intermediary devices.

The term “adjacent” here generally refers to a position of a thing being next to (e.g., immediately next to or close to with one or more things between them) or adjoining another thing (e.g., abutting it).

The term “circuit” or “module” may refer to one or more passive and/or active components that are arranged to cooperate with one another to provide a desired function.

The term “signal” may refer to at least one current signal, voltage signal, magnetic signal, or data/clock signal. The meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”

Here, the term “analog signal” generally refers to any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.

Here, the term “digital signal” generally refers to a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal.

The term “scaling” generally refers to converting a design (schematic and layout) from one process technology to another process technology and subsequently being reduced in layout area. The term “scaling” generally also refers to downsizing layout and devices within the same technology node. The term “scaling” may also refer to adjusting (e.g., slowing down or speeding up—i.e. scaling down, or scaling up respectively) of a signal frequency relative to another parameter, for example, power supply level.

The terms “substantially,” “close,” “approximately,” “near,” and “about,” generally refer to being within +/−10% of a target value. For example, unless otherwise specified in the explicit context of their use, the terms “substantially equal,” “about equal” and “approximately equal” mean that there is no more than incidental variation between among things so described. In the art, such variation is typically no more than +/−10% of a predetermined target value.

Unless otherwise specified the use of the ordinal adjectives “first,” “second,” and “third,” etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking or in any other manner.

For the purposes of the present disclosure, phrases “A and/or B” and “A or B” mean (A), (B), or (A and B). For the purposes of the present disclosure, the phrase “A, B, and/or C” means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “over,” “under,” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions. For example, the terms “over,” “under,” “front side,” “back side,” “top,” “bottom,” “over,” “under,” and “on” as used herein refer to a relative position of one component, structure, or material with respect to other referenced components, structures or materials within a device, where such physical relationships are noteworthy. These terms are employed herein for descriptive purposes only and predominantly within the context of a device z-axis and therefore may be relative to an orientation of a device. Hence, a first material “over” a second material in the context of a figure provided herein may also be “under” the second material if the device is oriented upside-down relative to the context of the figure provided. In the context of materials, one material disposed over or under another may be directly in contact or may have one or more intervening materials. Moreover, one material disposed between two materials may be directly in contact with the two layers or may have one or more intervening layers. In contrast, a first material “on” a second material is in direct contact with that second material. Similar distinctions are to be made in the context of component assemblies.

The term “between” may be employed in the context of the z-axis, x-axis or y-axis of a device. A material that is between two other materials may be in contact with one or both of those materials, or it may be separated from both of the other two materials by one or more intervening materials. A material “between” two other materials may therefore be in contact with either of the other two materials, or it may be coupled to the other two materials through an intervening material. A device that is between two other devices may be directly connected to one or both of those devices, or it may be separated from both of the other two devices by one or more intervening devices.

Here, multiple non-silicon semiconductor material layers may be stacked within a single fin structure. The multiple non-silicon semiconductor material layers may include one or more “P-type” layers that are suitable (e.g., offer higher hole mobility than silicon) for P-type transistors. The multiple non-silicon semiconductor material layers may further include one or more “N-type” layers that are suitable (e.g., offer higher electron mobility than silicon) for N-type transistors. The multiple non-silicon semiconductor material layers may further include one or more intervening layers separating the N-type from the P-type layers. The intervening layers may be at least partially sacrificial, for example to allow one or more of a gate, a source, or a drain to wrap completely around a channel region of one or more of the N-type and P-type transistors. The multiple non-silicon semiconductor material layers may be fabricated, at least in part, with self-aligned techniques such that a stacked CMOS device may include both a high-mobility N-type and P-type transistor with a footprint of a single FET (field effect transistor).

Here, the term “backend” generally refers to a section of a die which is opposite of a “frontend” and where an IC (integrated circuit) package couples to IC die bumps. For example, high-level metal layers (e.g., metal layer 6 and above in a ten-metal stack die) and corresponding vias that are closer to a die package are considered part of the backend of the die. Conversely, the term “frontend” generally refers to a section of the die that includes the active region (e.g., where transistors are fabricated) and low-level metal layers and corresponding vias that are closer to the active region (e.g., metal layer 5 and below in the ten-metal stack die example).

It is pointed out that those elements of the figures having the same reference numbers (or names) as the elements of any other figure can operate or function in any manner similar to that described, but are not limited to such.

FIG. 1 illustrates 3-input majority gate 100 using linear input capacitors resulting in non-rail-to-rail voltage swing at an input of a driver and leakage through the driver. 3-input majority gate 100 is a typical majority gate that uses linear input capacitors C1, C2, and C3 that are coupled to inputs a, b, and c, respectively, on one end and to a summing node n1 on another end. The summing node is where the majority function is performed e.g., Majority(a,b,c). The voltage developed on node n1 is then used to drive a CMOS driver 101. If CMOS driver 101 is an inverter, the output “out” provides a minority function of the inputs e.g., Minority(a,b,c). Here, the voltage developed on node n1 is not rail-to-rail voltage. As a result, standby current rushes through driver 101 because some of its transistors are not fully off due to the non-rail-to-rail voltage on node n1. As such, energy is wasted and 3-input majority gate 100 becomes unsuitable gate for use in any low power applications.

FIG. 2 illustrates timing diagram 200 showing operation of 3-input majority gate of FIG. 1 resulting in high static leakage. Timing diagram 200 shows digital input signals for inputs a, b, and c. Depending on the logic levels of inputs a, b, and c, a voltage is developed on summing node n1. This voltage is illustrated by waveform Maj(a,b,c). The voltage driven by inverter 101 on node “out” is the minority output, Min(a,b,c). The last waveform in the stack of waveforms shows the impact of using linear input capacitors as the basis of performing a majority function. When the voltage on node n1 is between Vdd and ground, crowbar current (also referred to as standby current) passes through the supply rail to the ground in CMOS driver 101. This crowbar current is substantially larger than leakage current (e.g., current through CMOS driver 101 when all its devices are off). As a result, 3-input majority gate 100 becomes unsuitable gate for use in any low power applications.

FIG. 3 illustrates a set of plots showing charge transfer function for non-linear capacitors compared to a linear capacitor. Plot 300 compares the transfer function for a linear capacitor, a paraelectric capacitor (a non-linear capacitor) and a ferroelectric capacitor (a non-linear capacitor). Here, x-axis is input voltage or voltage across the capacitor, while the y-axis is the charge on the capacitor. Plot 320 shows the charge and voltage relationship for a ferroelectric capacitor. A capacitor with ferroelectric material (also referred to as a FEC) is a non-linear capacitor with its potential V_(F)(Q_(F)) as a cubic function of its charge. Plot 320 illustrates characteristics of a FEC. Plot 320 is a charge-voltage (Q-V) plot for a block of Pb(Zr_(0.5)Ti_(0.5))O₃ of area (100 nm)² and thickness 20 nm (nanometer). Plot 320 shows local extrema at +/−V_(o) indicated by the dashed lines. Here, the term V_(c) is the coercive voltage. In applying a potential V across the FEC, its charge can be unambiguously determined only for |V|>V_(o). Otherwise, the charge of the FEC is subject to hysteresis effects.

FIG. 4 illustrates 3-input majority gate 400 using non-linear input capacitors, in accordance with some embodiments. In some embodiments, 3-input majority gate 400 comprises non-linear input capacitors C1 n 1, C2 n 1, and C3 n 1 that receives digital signals a, b, and c, respectively. Here, signal names and node names are interchangeably used. For example, ‘a’ refers to node ‘a’ or signal ‘a’ depending on the context of the sentence. One end or terminal of capacitor C1 n 1 is coupled to node a while the other end of capacitor C1 n 1 is coupled to summing node Vs. The same is true for other non-linear capacitors C2 n 1 and C3 n 1 as shown. In some embodiments, 3-input majority gate 400 comprises a driver circuitry 101. In this example, driver circuitry 101 is an inverter. In other embodiments, other types of driver circuitries can be used such as NAND gate, NOR gate, multiplexer, buffer, and other logic gates. The majority function is performed at summing node Vs as Majority(a,b,c). In this example, since driver 101 is an inverter, minority function is performed at output “out” as Minority(a,b,c).

In some embodiments, in addition to the gate capacitance of driver circuitry 101, an additional linear capacitor CL is coupled to summing node Vs and ground as shown. In some embodiments, this linear capacitor CL is a non-ferroelectric capacitor. In some embodiments, the non-ferroelectric capacitor includes one of: dielectric capacitor, para-electric capacitor, or non-linear dielectric capacitor. A dielectric capacitor comprises first and second metal plates with a dielectric between them. Examples of such dielectrics are: HfO, ABO3 perovskites, nitrides, oxy-fluorides, oxides, etc. A para-electric capacitor comprises first and second metal plates with a para-electric material between them. In some embodiments, f-orbital materials (e.g., lanthanides) are doped to the ferroelectric materials to make paraelectric material. Examples of room temperature paraelectric material include: SrTiO3, Ba(x)Sr(y)TiO3 (where x is −0.5, and y is 0.95)), HfZrO2, Hf—Si—O, La-substituted PbTiO3, PMN-PT based relaxor ferroelectrics. A dielectric capacitor comprises first and second metal plates with non-linear dielectric capacitor between them. The range for dielectric constant is 1.2 to 10000. The capacitor CL can be implemented as MIM (metal-insulator-metal) capacitor technology, transistor gate capacitor, hybrid of metal capacitors or transistor capacitor. The capacitor CL can be implemented as MIM (metal-insulator-metal) capacitor technology, transistor gate capacitor, or hybrid of metal capacitors or transistor capacitor.

In some embodiments, the non-linear input capacitors C1 n 1, C2 n 1, and C3 n 1 comprise non-linear polar material. In some embodiments, the non-linear polar material includes one of: ferroelectric (FE) material, para-electric material, relaxor ferroelectric, or non-linear dielectric. In various embodiments, para-electric material is the same as FE material but with chemical doping of the active ferroelectric ion by an ion with no polar distortion. In some cases, the non-polar ions are non-s orbital ions formed with p, d, f external orbitals. In some embodiments, non-linear dielectric materials are same as para-electric materials, relaxors, and dipolar glasses.

In some embodiments, f-orbital materials (e.g., lanthanides) are doped to the ferroelectric material to make paraelectric material. Examples of room temperature paraelectric material include: SrTiO3, Ba(x)Sr(y)TiO3 (where x is −0.5, and y is 0.95), HfZrO2, Hf—Si—O, La-substituted PbTiO3, and PMN-PT based relaxor ferroelectrics.

In various embodiments, the FE material can be any suitable low voltage FE material that allows the FE material to switch its state by a low voltage (e.g., 100 mV). In some embodiments, the FE material comprises a perovskite of the type ABO3, where ‘A’ and ‘B’ are two cations of different sizes, and ‘O’ is oxygen which is an anion that bonds to both the cations. Generally, the size of A atoms is larger than the size of B atoms. In some embodiments, the perovskite can be doped (e.g., by La or Lanthanides). Perovskites can be suitably doped to achieve a spontaneous distortion in a range of 0.3 to 2%. For example, for chemically substituted lead titanate such as Zr in Ti site; La, Nb in Ti site, the concentration of these substitutes is such that it achieves the spontaneous distortion in the range of 0.3 to 2%. For chemically substituted BiFeO3, BiCrO3, BiCoO3 class of materials, La or rare earth substitution into the Bi site can tune the spontaneous distortion. In some embodiments, perovskite includes one of: BaTiO3, PbTiO3, KNbO3, or NaTaO3.

Threshold in the FE material has a highly non-linear transfer function in the polarization vs. voltage response. The threshold is related to: a) non-linearity of switching transfer function; and b) the squareness of the FE switching. The non-linearity of switching transfer function is the width of the derivative of the polarization vs. voltage plot. The squareness is defined by the ratio of the remnant polarization to the saturation polarization; perfect squareness will show a value of 1.

The squareness of the FE switching can be suitably manipulated with chemical substitution. For example, in PbTiO3 a P-E (polarization-electric field) square loop can be modified by La or Nb substitution to create an S-shaped loop. The shape can be systematically tuned to ultimately yield a non-linear dielectric. The squareness of the FE switching can also be changed by the granularity of the FE layer. A perfect epitaxial, single crystalline FE layer will show higher squareness (e.g., ratio is closer to 1) compared to a poly crystalline FE. This perfect epitaxial can be accomplished by the use of lattice matched bottom and top electrodes. In one example, BiFeO (BFO) can be epitaxially synthesized using a lattice matched SrRuO3 bottom electrode yielding P-E loops that are square. Progressive doping with La will reduce the squareness.

In some embodiments, the FE material is contacted with a conductive metal oxide that includes one of the conducting perovskite metallic oxides exemplified by: La—Sr—CoO3, SrRuO3, La—Sr—MnO3, YBa2Cu3O7, Bi2Sr2CaCu2O8, LaNiO3, and ReO3.

In some embodiments, the FE material comprises a stack of layers including low voltage FE material between (or sandwiched between) conductive oxides. In various embodiments, when FE material is a perovskite, the conductive oxides are of the type AA′BB′O₃. A′ is a dopant for atomic site A, it can be an element from the Lanthanides series. B′ is a dopant for atomic site B, it can be an element from the transition metal elements especially Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn. A′ may have the same valency of site A, with a different ferroelectric polarizability.

In some embodiments, the FE material comprises hexagonal ferroelectrics of the type h-RMnO3, where R is a rare earth element such as: cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y). The ferroelectric phase is characterized by a buckling of the layered MnO5 polyhedra, accompanied by displacements of the Y ions, which lead to a net electric polarization. In some embodiments, hexagonal FE includes one of: YMnO3 or LuFeO3. In various embodiments, when the FE material comprises hexagonal ferroelectrics, the conductive oxides adjacent to the FE material are of A2O3 (e.g., In2O3, Fe2O3) and AB2O3 type, where ‘A’ is a rare earth element and B is Mn.

In some embodiments, FE material comprises improper FE material. An improper ferroelectric is a ferroelectric where the primary order parameter is an order mechanism such as strain or buckling of the atomic order. Examples of improper FE material are LuFeO3 class of materials or super lattice of ferroelectric and paraelectric materials PbTiO3 (PTO) and SnTiO3 (STO), respectively, and LaAlO3 (LAO) and STO, respectively. For example, a super lattice of [PTO/STO]n or [LAO/STO]n, where ‘n’ is between 1 to 100. While various embodiments here are described with reference to ferroelectric material for storing the charge state, the embodiments are also applicable for paraelectric material. For example, the capacitor of various embodiments can be formed using paraelectric material instead of ferroelectric material.

In some embodiments, the FE material includes one of: Hafnium (Hf), Zirconium (Zr), Aluminum (Al), Silicon (Si), their oxides or their alloyed oxides. In some embodiments, FE material includes one of: Al(1-x)Sc(x)N, Ga(1-x)Sc(x)N, Al(1-x)Y(x)N or Al(1-x-y)Mg(x)Nb(y)N, y doped HfO2, where x includes one of: Al, Ca, Ce, Dy, Er, Gd, Ge, La, Sc, Si, Sr, Sn, or Y, wherein ‘x’ is a fraction. In some embodiments, the FE material includes Bismuth ferrite (BFO), lead zirconate titanate (PZT), BFO with doping material, or PZT with doping material, wherein the doping material is one of Nb or relaxor ferroelectrics such as PMN-PT.

In some embodiments, the FE material includes Bismuth ferrite (BFO), BFO with a doping material where in the doping material is one of Lanthanum, or any element from the lanthanide series of the periodic table. In some embodiments, the FE material includes lead zirconium titanate (PZT), or PZT with a doping material, wherein the doping material is one of La, Nb. In some embodiments, the FE material includes a relaxor ferro-electric including one of lead magnesium niobate (PMN), lead magnesium niobate-lead titanate (PMN-PT), lead lanthanum zirconate titanate (PLZT), lead scandium niobate (PSN), Barium Titanium-Bismuth Zinc Niobium Tantalum (BT-BZNT), or Barium Titanium-Barium Strontium Titanium (BT-BST).

In some embodiments, the FE material includes Hafnium oxides of the form, Hf1-x Ex Oy where E can be Al, Ca, Ce, Dy, er, Gd, Ge, La, Sc, Si, Sr, Sn, or Y. In some embodiments, FE material 105 includes Niobate type compounds LiNbO3, LiTaO3, Lithium iron Tantalum Oxy Fluoride, Barium Strontium Niobate, Sodium Barium Niobate, or Potassium strontium niobate.

In some embodiments, the FE material comprises multiple layers. For example, alternating layers of [Bi2O2]2+, and pseudo-perovskite blocks (Bi4Ti3O12 and related Aurivillius phases), with perovskite layers that are n octahedral layers in thickness can be used.

In some embodiments, the FE material comprises organic material. For example, Polyvinylidene fluoride or polyvinylidene difluoride (PVDF). The FE material is between two electrodes. These electrodes are conducting electrodes. In some embodiments, the electrodes are perovskite templated conductors. In such a templated structure, a thin layer (e.g., approximately 10 nm) of a perovskite conductor (such as SrRuO3) is coated on top of IrO2, RuO2, PdO2, or PtO2 (which have a non-perovskite structure but higher conductivity) to provide a seed or template for the growth of pure perovskite ferroelectric at low temperatures. In some embodiments, when the ferroelectric comprises hexagonal ferroelectric material, the electrodes can have hexagonal metals, spinels, or cubic metals. Examples of hexagonal metals include: PtCoO2, PdCoO2, and other delafossite structured hexagonal metallic oxides such as Al-doped ZnO. Examples of spinels include Fe3O4 and LiV2O4. Examples of cubic metals include Indium Tin Oxide (ITO) such as Sn-doped In2O3.

The majority function is performed at the summing node Vs, and the resulting voltage is projected on to capacitance of driver circuitry 101. For example, the majority function of the currents (I_(a), I_(b), and I_(c)) on node Vs results in a resultant current that charges capacitor 105. Table 1 illustrates the majority function f(Majority a, b, c).

TABLE 1 a b c Vs (f(Majority a, b, c)) 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 1 1 0 0 0 1 0 1 1 1 1 0 1 1 1 1 1

The charge developed on node Vs produces a voltage and current that is the output of the majority gate 400. Any suitable driver 101 can drive this output. For example, a non-FE logic, FE logic, CMOS logic, BJT logic, etc. can be used to drive the output to a downstream logic. Examples of the drivers include inverters, buffers, NAND gates, NOR gates, XOR gates, amplifiers, comparators, digital-to-analog converters, analog-to-digital converters, multiplexers, etc.

While FIG. 4 illustrates a 3-input majority gate, the same concept can be extended to more than 3 inputs to make an N-input majority gate, where N is greater than 2. In various embodiments, ‘N’ is an odd number. For example, a 5-input majority gate is similar to a input majority gate 400 but for additional inputs ‘d’ and ‘e’. These inputs can come from the same drivers or from different drivers.

In some embodiments, the 3-input majority gate can be configured as a fast inverter with a much faster propagation delay compared to a similar sized (in terms of area footprint) CMOS inverter. This is particularly useful when the inputs have a significantly slower slope compared to the propagation delay through the non-linear input capacitors. One way to configurate the 3-input majority gate as an inverter is to set one input to a logic high (e.g., b=1) and set another input to a logic low (e.g., b=0). The third input is the driving input which is to be inverted. The inversion will be at the Vs node. The same technique can also be applied to N-input majority gate, where ‘N’ is 1 or any other odd number. In an N-input majority gate, (N−1)/2 inputs are set to ‘1’ and (N−1)/2 inputs are set to ‘0’, and one input is used to decide the inversion function. It will be appreciated that the various embodiments are described as a majority gate, the same concepts are applicable to a minority gate. In a minority gate the driving circuitry is an inverting circuitry coupled to the summing node Vs. The minority function is seen at the output of the inverting circuitry.

In some embodiments, (2N−1) input majority gate can operate as an N-input AND gate where (N−1) inputs of the majority gate are set to zero. The AND function will be seen at the summing node Vs. Similarly, N-input NAND, OR, NOR gates can be realized. In various embodiments, the summing node Vs is driven by a driver circuitry (e.g., inverter, buffer, NAND gate, AND gate, OR gate, NOR gate, or any other logic circuitry). However, driver circuitry 101 can be replaced with another majority or minority gate. In one such embodiment, the storage node Vs is directly coupled to a non-linear capacitor of another majority or minority gate.

Any logic function ƒ(x₁, x₂, . . . x_(n))can be represented by two levels of logic as given by the min-term expansion: ƒ(x ₁ ,x ₂ , . . . x _(n))=V _(c) ₁ _(,c) ₂ _(, . . . c) _(n) ƒ(x ₁ ,x ₂ , . . . x _(n)){circumflex over ( )}x ₁ ^(c) ¹ {circumflex over ( )}x ₂ ^(c) ² {circumflex over ( )}x ₃ ^(c) ³ . . . {circumflex over ( )}x _(n) ^(c) ^(n) where C_(i) is either 0 or 1. When C_(i) is 1, x_(i) ^(c) ^(i) =x_(i) (the input is used in its original form). When C_(i) is 0, x_(i) ^(c) ^(i) =x_(i) (the input is used in its inverted form). The first level of logic is represented by at most 2^(n) AND gates (Δ), one for each of the 2^(n) possible combinations of 0 and 1 for C₁, C₂, . . . . C_(n). The second level of logic is represented by a single OR gate (V). Each operand of the OR gate is a representation of a row in the truth table for ƒ(x₁, x₂, . . . x_(n)).

A (2N−1)-input majority gate can represent an N-input AND gate, by tying (N−1) of the majority gate's inputs to a ground level. Similarly, a (2N−1)-input majority gate can represent an N-input OR gate, by tying (N−1) of the majority gate's inputs to a supply level (Vdd). Since a majority gate can represent AND and OR gates, and the inputs to the AND and OR gates are either original or inverted forms of the input digital signals, any logic function can be represented by majority gates and inverters only, in accordance with some embodiments.

FIG. 5 illustrates 3-input majority gate 500 using non-linear input capacitors and no driver circuitry, in accordance with some embodiments. In some embodiments, the summing node Vs is not coupled to a CMOS driver (e.g., buffer, inverter, NAND gate, or any other CMOS logic gate). In one example, Vs is coupled to another majority or minority gate. For instance, Vs is coupled to a terminal of another non-linear capacitor of another majority or minority gate.

FIG. 6 illustrates a set of plots 600 and 620 showing logic state separation for non-linear capacitors compared to a linear capacitor, in accordance with some embodiments. The sum of all charges must be zero to determine Vs for given sets of inputs V_(a), V_(b), and V_(e) (which are voltages on nodes a, b, and c, respectively) as follows: ΣQ(V _(s))=Q _(a)(V _(a) −V _(s))+Q _(b)(V _(b) −V _(s))+Q _(c)(V _(c) −V _(s))−C _(L) V _(s)=0

Plot 600 shows sum of charges for different values of V_(a), V_(b), and V_(c) when the input capacitors are linear capacitors as in FIG. 1. Plot 620 shows sum of charges for different values of V_(a), V_(b), and V_(c) when the input capacitors are non-linear capacitors as in FIG. 4. The different values are: V_(a)=0, V_(b)=0, and V_(c)=0; V_(a)=1, V_(b)=0, and V_(c)=1; V_(a)=1, V_(b)=0, and V_(c)=0; and V_(a)=1, V_(b)=1, and V_(c)=1.

Plot 600 shows two points 601 and 602 for inputs (1,0,0) for (Va, Vb, and Vc) and (1,1,0) which do not provide a clear logic level of 0 or 1. Inputs (1,0,0) for (Va, Vb, and Vc) are expected to generate a 0 on node n1, but results in a higher voltage closer to 0.3, which is too close to a threshold voltage of transistor of driver circuitry 101. Inputs (1,1,0) for (Va, Vb, and Vc) are expected to generate a 1 on node n1, but results in a lower voltage closer to 0.7. Such voltages on node n1 result in crowbar current through driver circuitry 101. Plot 620 shows the desired majority gate solution where all input combinations result in clear voltage levels of 0 (e.g., 621) or 1 (622).

FIG. 7A illustrates timing diagram 700 for a 3-input majority or minority gate using ferroelectric input capacitors, in accordance with some embodiments. FIG. 7B illustrates timing diagram 720 from a 3-input majority gate or minority gate using paraelectric input capacitors, in accordance with some embodiments. In both cases, the voltage on node Vs shows a rail-to-rail voltage for majority function. Such rail-to-rail voltage suppresses crowbar current through driver circuitry 101. For some input combinations, using ferroelectric material can suppress leakage current below CMOS leakage level compared to using paraelectric material for the input capacitors.

FIG. 8 illustrates a 2-input AND or NAND gate 800 using non-linear input capacitors, in accordance with some embodiments. Gate 800 is similar to gate 400 but for providing a constant voltage to one of the inputs, here input ‘c’. When input ‘c’ is set to ground level (e.g., 0 V), the majority function on node Vs is an AND function of inputs a and b, and the resulting output of inverter 101 is a NAND function of inputs a and b, in accordance with some embodiments.

FIG. 9 illustrates a 2-input OR or NOR gate 900 using non-linear input capacitors, in accordance with some embodiments. Gate 900 is similar to gate 400 but for providing a constant voltage to one of the inputs, here input ‘c’. When input ‘c’ is set to supply level (e.g., Vdd), the majority function on node Vs is an OR function of inputs a and b, and the resulting output of inverter 101 is a NOR function of inputs a and b, in accordance with some embodiments.

FIG. 10 illustrates a majority gate based XOR gate 1000 using non-linear input capacitors, in accordance with some embodiments. XOR gate 1000 is a 2-input XOR gate that performs XOR function on inputs a and b. In various embodiments, XOR gate 1000 comprises non-linear input capacitors C1 n 1, C2 n 1, C3 n 1, C4 n 1, C5 n 1, and C6 n 1, inverter 101, and non-linear output capacitors C7 n 1, C8 n 1, and C9 n 1. Capacitors C1 n 1, C2 n 1, and C3 n 1 receive inputs a, b, and 0, and perform majority AND function on node Vs1 like AND gate 800. Capacitors C4 n 1, C5 n 1, and C6 n 1 receive inputs a, b, and Vdd, and perform majority OR function on node Vs2 like OR gate 900. The NAND output on node out1 is received by output capacitor C7 n 1. The OR output on node Vs2 is received by capacitor C8 n 1. Capacitor C9 n 1 receives a predetermined input 0 in this example. The majority function on node out3 is an AND of out1, out2, and 0. In some embodiments, instead of driving voltage on node Vs2 to out2, buffer 1001 is used between nodes Vs2 and out2. In some embodiments, instead of driving output out3 as the XOR output, buffer 1002 is used to output the XOR output on node out. In some embodiments, Vs2 is directly connected to node out2. In some embodiments, out3 is directly connected to node out. In some embodiments, linear or non-linear capacitors CL1, CL2, and CL3 are added on the summing nodes Vs1, Vs2, and out3, respectively. By swapping the voltages ‘0’ and ‘Vdd’ different logic functions can be realized, in accordance with various embodiments.

FIG. 11 illustrates a majority gate based XOR gate 1100 using non-linear input capacitors and with output driver, in accordance with some embodiments. Compared to XOR gate 1000, here inverter 101 is removed and AND output on Vs1 is directly provided to capacitor C7 n 1. In this case, node out1 is shorted to node Vs1. In some embodiments, buffer 1101 is used to drive the output on node Vs1 to node out1. In some embodiments, Vs2 node provides a majority OR function of inputs a and b. The result of majority OR is then inverted by inverter 1001 to generate a NOR function on node out2. Out2 then drives capacitors C8 n 1. In some embodiments, in input to capacitor C9 n 1 is Vdd. The function on node out3 is an OR function of out1 and out2, which is inverted by inverter 1002 to generate the XOR logic. By swapping the voltages ‘0’ and ‘Vdd’ different logic functions can be realized, in accordance with various embodiments. In some embodiments, Vs2 is directly connected to node out2. In some embodiments, out3 is directly connected to node out.

FIG. 12 illustrates a majority gate based complex logic gate 1200 with non-linear input capacitors, in accordance with some embodiments. Complex logic gate 1200 is configured as an And-Or-Invert (AOI) gate, which comprises non-linear input capacitors C1 n 1, C2 n 1, and C3 n 1 coupled to inputs a, b, and 0, respectively. The summing node Vs1 provides an AND function of inputs a and b. Gate 1200 further comprises output non-linear capacitors C4 n 1, C5 n 1, and C6 n 1, and output driver (e.g., inverter 1202). In some embodiments, Vs1 is directly coupled to node out1 (e.g., out1 and Vs1 are shorted together). In some embodiments, buffer 1201 drives the voltage on Vs1 to node ou1. In some embodiments, capacitor C4 n 1 receives input c while capacitor C6 n 1 receives input Vdd. The function on node Vs2 is an OR of c and out1, which when inverted by inverter 1202 generates an AOI output on node out. By swapping the voltages ‘0’ and ‘Vdd’ different logic functions can be realized, in accordance with various embodiments. For example, Or-AND-Inverter, 3-input NOR, 3-input NAND, etc. can be realized using gate 1200. Compared to a CMOS AOI gate that uses at least 6 transistors and is only able to do one function (AOI), here multiple functions can be realized using 6 non-linear capacitors and 2 transistors (when buffer 1201 is removed). In some embodiments, linear capacitors CL1 and CL2 are added on the summing nodes to hold the voltage.

FIG. 13 illustrates top down layout and corresponding cross-section of a 3-input majority gate, respectively, in accordance with some embodiments. Layout 1300 illustrates a compact layout of 3-input majority gate of FIG. 4 with a pitch of two minimum sized transistors MNinv and MPinv of inverter 101. In some embodiments, non-linear input capacitors C1 n 1, C2 n 1, and C3 n 1 are positioned in the same set of layers. For example, non-linear capacitors C1 n 1, C2 n 1, and C3 n 1 are positioned in the place of via for metal layer 1 (M1) to metal layer 2 (M2).

In some embodiments, transistors MNinv and MPinv are fabricated in the frontend of the die. Inputs a, b, and c are on M2. Common node Vs (also referred to as charge integration layer or node) is on M1. The common node Vs1 is shared by non-linear capacitors (C1 n 1, C2 n 1, and C3 n 1) and/or non-linear polar capacitor 105. While non-linear capacitors C1 n 1, C2 n 1, and C3 n 1 are positioned in location of M1-via-M2, they can be further located in the backend of the die. For example, non-linear capacitors C1 n 1, C2 n 1, and C3 n 1, can be positioned in M4-Via-M5 or higher. As such, lower metal layers are freed up for routing of other signals.

Transistors MNinv and MPinv can be planar or non-planar transistors. In some embodiments, transistors MNinv and MPinv can be formed in the frontend or backend. In some embodiments, MNinv and MPinv are stacked transistors. In some embodiments, one or more of non-linear capacitors C1 n 1, C2 n 1, and C3 n 1, are formed in the frontend or backend. The transistors here can be Square Wire, Rectangular Ribbon Transistors, Gate All Around Cylindrical Transistors, Tunneling FETs ferroelectric FETs (FeFETs), bi-polar transistors (BJT), BiCMOS, or other devices implementing transistors functionality, for instance, carbon nanotubes or spintronic devices. In some embodiments, the transistors are typical metal oxide semiconductor (MOS) transistors or their derivative including Tri-Gate and FinFET transistors. While MOSFET have symmetrical source and drain terminals, TFET device has asymmetric source and drain terminals.

Transistors MNinv and MPinv are formed in/on substrate 1301, and comprises respective source 1302, drain 1303, channel region 1304, source contact 1308 a, drain contact 1308 b, and gate comprising gate dielectric 1305, gate liners 1306 a and 1306 b; gate metal 1307.

Substrate 1301 includes a suitable semiconductor material such as: single crystal silicon, polycrystalline silicon and silicon on insulator (SOI). In one embodiment, substrate 1301 includes other semiconductor materials such as: Si, Ge, SiGe, or a suitable group III-V or group III-N compound. Substrate 1301 may also include semiconductor materials, metals, dopants, and other materials commonly found in semiconductor substrates.

In some embodiments, source region 1302 and drain region 1303 for each transistor are formed within substrate 1301 adjacent to the gate stack of the transistor. In various embodiments, p-type transistors MPinv is formed in an n-well, which is in substrate 1301. The source region 1302 and drain region 1303 are generally formed using either an etching/deposition process or an implantation/diffusion process.

In the etching and/or deposition process, substrate 1301 may first be etched to form recesses at the locations of the source 1302 and drain 1303 regions. An epitaxial deposition process may then be carried out to fill the recesses with material that is used to fabricate the source region 1302 and drain region 1303. In the implantation/diffusion process, dopants such as boron, aluminum, antimony, phosphorous, or arsenic may be ion-implanted into the substrate to form the source region 1302 and drain region 1303. An annealing process that activates the dopants and causes them to diffuse further into substrate 1301 typically follows the ion-implantation process.

In some embodiments, one or more layers of metal and/or metal alloys are used to form the source region 1302 and drain region 1303. In some embodiments, source region 1302 and drain region 1303 are formed using one or more alternate semiconductor materials such as germanium or a suitable group III-V compound. In some embodiments, source region 1302 and drain region 1303 are fabricated using a silicon alloy such as silicon germanium or silicon carbide. In some embodiments, the epitaxially deposited silicon alloy is doped in-situ with dopants such as boron, arsenic, or phosphorous.

The semiconductor material for channel region 1304 may have the same material as substrate 1301 or n-well for a p-type transistor MPinv, in accordance with some embodiments. In some embodiments, channel region 604 includes one of: Si, SiGe, Ge, and GaAs.

The high-k dielectric material may include elements such as: zinc, niobium, scandium, lean yttrium, hafnium, silicon, strontium, oxygen, barium, titanium, zirconium, tantalum, aluminum, and lanthanum. Examples of high-k materials that may be used in the gate dielectric layer include: lead zinc niobate, hafnium oxide, lead scandium tantalum oxide, hafnium silicon oxide, yttrium oxide, aluminum oxide, lanthanum oxide, barium strontium titanium oxide, lanthanum aluminum oxide, titanium oxide, zirconium oxide, tantalum oxide, and zirconium silicon oxide. In some embodiments, when a high-k material is used, an annealing process is used on the gate dielectric layer 1305 to improve its quality.

In some embodiments, a pair of liner layers (sidewall liners) 606 a/b are formed on opposing sides of the gate stack that bracket the gate stack. The pair of liner layers 1306 a/b are formed from a material such as: silicon oxynitride, silicon nitride, silicon nitride doped with carbon, or silicon carbide. Processes for forming sidewall liners are well-known in the art and generally include deposition and etching process operations. In some embodiments, a plurality of liner pairs may be used. For example, two pairs, three pairs, or four pairs of sidewall liners may be formed on opposing sides of the gate stack.

Gate metal layer 1307 may comprise at least one P-type work-function metal or N-type work-function metal, depending on whether the transistor is to be a p-type or an n-type transistor. Gate metal layer 1307 may comprise a stack of two or more metal layers, where one or more metal layers are work-function metal layers and at least one metal layer is a conductive fill layer.

For an n-type transistor, metals that may be used for the gate metal layer 1307 include: aluminum carbide, tantalum carbide, zirconium carbide, and hafnium carbide. In some embodiments, metal for gate metal layer 1307 for n-type transistor include: aluminum, hafnium, zirconium, titanium, tantalum, and their alloys. An n-type metal layer will enable the formation of an n-type gate metal layer 1307 with a work function that is between about 3.9 eV and about 4.2 eV. In some embodiments, metal of layer 1307 includes one of: TiN, TiSiN, TaN, Cu, Al, Au, W, TiSiN, or Co. In some embodiments, metal of layer 107 includes one or more of: Ti, N, Si, Ta, Cu, Al, Au, W, or Co.

For a p-type transistor, metals that are used for gate metal layer 1307 include, but are not limited to, ruthenium, palladium, platinum, cobalt, nickel, and conductive metal oxides. An example of conductive oxide includes ruthenium oxide. A p-type metal layer will enable the formation of a p-type gate metal layer 1307 with a work function that is between about 4.9 eV and about 5.2 eV.

Any suitable material can be used for drain and source contacts 1308 a/b and via 1309 a/b. For example, one or more of Ti, N, Si, Ta, Cu, Al, Au, W, or Co can be used for drain and source contacts 1308 a/b and via 1309 a/b. The gate electrodes 1307 may be connected to one another directly or through vias and metal layers. Drivers (not shown) drive signals on nodes a, b, and c. The gates 1307 of MPinv and MNinv are coupled together. For example, gate electrodes 1307 may be connected to node Vs directly or through vias and metal layers 1316 and 1317, respectively.

FIGS. 14A-C illustrate a 2-input AND (or NAND) gate 1400 comprising two non-linear capacitors, associated timing diagram 1420, and associated charges 1430, in accordance with some embodiments. In some embodiments, a 2-input AND gate (which can be transformed into a NAND gate) comprises a first non-linear capacitor C1 n 1 and a second non-linear capacitor C1 n 1. The first non-linear capacitor C1 n 1 receives a first input ‘a’ (e.g., a digital input from a driver or another majority or minority gate). The second non-linear capacitor C2 n 1 receives a first input ‘b’ (e.g., a digital input from a driver or another majority or minority gate). The two non-linear capacitors C1 n 1 and C2 n 1 connect to a summing node Vs where the AND function is performed. The result of the AND operation can be received by any majority or minority gate in accordance with some embodiments. In some embodiments. the result of the AND function can be inverted or buffered. In some embodiments, node Vs is directly connected to another majority gate (e.g., a non-linear capacitor of another gate). In some embodiments, inverters 101 and 1401 are removed.

In one example, the summing node Vs is coupled to an input of an inverter 101 that generates an output “out” which provided a NAND function of the inputs ‘a’ and ‘b’. In some embodiments, the output “out” is inverted by inverter 1401 to generate an output “out_b” which is an AND function of ‘a’ and ‘b’ (illustrated as AND_b(a,b)). The AND gate of FIG. 14 mitigates the short circuit current leakage issue caused by non-rail-to-rail voltages on node Vs when linear input capacitors are used. When linear capacitors are used as input capacitors, when input ‘a’ is a 1 and input ‘b’ is a zero, the voltage on Vs is half of input ‘a’ and input ‘b’, which causes metastability. The non-linear input capacitors such as FE based capacitors or paraelectric based capacitors (or any other non-linear dielectric) result in near rail-to-rail voltage on node Vs which controls any crowbar current and/or leakage current through subsequent driver circuitry like inverter 101. Here, the metastability problem is avoided by using non-linear input capacitors. Plot 1420 shows the timing diagram of AND gate 1400. Here, the low voltage on node Vs is low enough to trip inverter 101 to a high logic level output on node “out”, and the high voltage on node Vs is high enough to trip inverter 101 to a low logic level output on node “out”. As such, AND gate 1400 shows proper logic function and operation using two non-linear input capacitors. Plot 1430 is similar to plot 1420, but also shows the positive and negative charges on non-linear input capacitors C1 n 1 and C2 n 1.

FIG. 15 illustrates complex logic gate 1500 implemented using a 5-input majority gate, in accordance with some embodiments. In some embodiments, an AOI (and-or-invert) logic comprises a 5-input majority gate. The 5-input majority gate includes non-linear capacitors C1 n 1, C2 n 1, C3 n 1, C4 n 1, and C5 n 1 and driving circuitry 101 coupled as shown. In various embodiments, two of the non-linear capacitors receives the same input. Here, capacitors C3 n 1 and C4 n 1 receive input ‘c’. In various embodiments, C5 n 1 is coupled to Vdd to produce an OR function at node Vs, where the OR function is OR(AND(a,b),c). In some embodiments, other logic gates can be realized by changing Vdd to ground for capacitor C5 n 1, and/or changing other inputs.

FIG. 16 illustrates a system-on-chip (SOC) 1600 that uses the majority logic gates having non-linear input capacitors, in accordance with some embodiments. SOC 1600 comprises memory 1601 having static random-access memory (SRAM) or FE based random access memory FE-RAM, or any other suitable memory. The memory can be non-volatile (NV) or volatile memory. Memory 1601 may also comprise logic 1603 to control memory 1602. For example, write and read drivers are part of logic 1603. These drivers and other logic are implemented using the majority or threshold gates of various embodiments. The logic can comprise majority or threshold gates and traditional logic (e.g., CMOS based NAND, NOR etc.).

SOC further comprises a memory I/O (input-output) interface 1604. The interface may be double-data rate (DDR) compliant interface or any other suitable interface to communicate with a processor. Processor 1605 of SOC 1600 can be a single core or multiple core processor. Processor 1605 can be a general-purpose processor (CPU), a digital signal processor (DSP), or an Application Specific Integrated Circuit (ASIC) processor. In some embodiments, processor 1605 is an artificial intelligence (AI) processor (e.g., a dedicated AI processor, a graphics processor configured as an AI processor). In various embodiments, processor 1605 is a processor circuitry which is to execute one or more instructions.

AI is a broad area of hardware and software computations where data is analyzed, classified, and then a decision is made regarding the data. For example, a model describing classification of data for a certain property or properties is trained over time with large amounts of data. The process of training a model requires large amounts of data and processing power to analyze the data. When a model is trained, weights or weight factors are modified based on outputs of the model. Once weights for a model are computed to a high confidence level (e.g., 95% or more) by repeatedly analyzing data and modifying weights to get the expected results, the model is deemed “trained.” This trained model with fixed weights is then used to make decisions about new data. Training a model and then applying the trained model for new data is hardware intensive activity. In some embodiments, AI processor 405 has reduced latency of computing the training model and using the training model, which reduces the power consumption of such AI processor systems.

Processor 1605 may be coupled to a number of other chip-lets that can be on the same die as SOC 1600 or on separate dies. These chip-lets include connectivity circuitry 1606, I/O controller 1607, power management 1608, and display system 1609, and peripheral connectivity 1610.

Connectivity 1606 represents hardware devices and software components for communicating with other devices. Connectivity 1606 may support various connectivity circuitries and standards. For example, connectivity 1606 may support GSM (global system for mobile communications) or variations or derivatives, CDMA (code division multiple access) or variations or derivatives, TDM (time division multiplexing) or variations or derivatives, 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications Systems (UMTS) system or variations or derivatives, 3GPP Long-Term Evolution (LTE) system or variations or derivatives, 3GPP LTE-Advanced (LTE-A) system or variations or derivatives, Fifth Generation (5G) wireless system or variations or derivatives, 5G mobile networks system or variations or derivatives, 5G New Radio (NR) system or variations or derivatives, or other cellular service standards. In some embodiments, connectivity 1606 may support non-cellular standards such as WiFi.

I/O controller 1607 represents hardware devices and software components related to interaction with a user. I/O controller 1607 is operable to manage hardware that is part of an audio subsystem and/or display subsystem. For example, input through a microphone or other audio device can provide input or commands for one or more applications or functions of SOC 1600. In some embodiments, I/O controller 1607 illustrates a connection point for additional devices that connect to SOC 1600 through which a user might interact with the system. For example, devices that can be attached to the SOC 1600 might include microphone devices, speaker or stereo systems, video systems or other display devices, keyboard or keypad devices, or other I/O devices for use with specific applications such as card readers or other devices.

Power management 1608 represents hardware or software that perform power management operations, e.g., based at least in part on receiving measurements from power measurement circuitries, temperature measurement circuitries, charge level of battery, and/or any other appropriate information that may be used for power management. By using majority and threshold gates of various embodiments, non-volatility is achieved at the output of these logic. Power management 1608 may accordingly put such logic into low power state without the worry of losing data. Power management may select a power state according to Advanced Configuration and Power Interface (ACPI) specification for one or all components of SOC 1600.

Display system 1609 represents hardware (e.g., display devices) and software (e.g., drivers) components that provide a visual and/or tactile display for a user to interact with the processor 1605. In some embodiments, display system 1609 includes a touch screen (or touch pad) device that provides both output and input to a user. Display system 1609 may include a display interface, which includes the particular screen or hardware device used to provide a display to a user. In some embodiments, the display interface includes logic separate from processor 1605 to perform at least some processing related to the display.

Peripheral connectivity 1610 may represent hardware devices and/or software devices for connecting to peripheral devices such as printers, chargers, cameras, etc. Peripheral connectivity 1610 may support communication protocols, e.g., PCIe (Peripheral Component Interconnect Express), USB (Universal Serial Bus), Thunderbolt, High Definition Multimedia Interface (HDMI), Firewire, etc.

Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” or “other embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments. The various appearances of “an embodiment,” “one embodiment,” or “some embodiments” are not necessarily all referring to the same embodiments. If the specification states a component, feature, structure, or characteristic “may,” “might,” or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the elements. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional elements.

Furthermore, the particular features, structures, functions, or characteristics may be combined in any suitable manner in one or more embodiments. For example, a first embodiment may be combined with a second embodiment anywhere the particular features, structures, functions, or characteristics associated with the two embodiments are not mutually exclusive.
